tf-multi-checkbox creates a list of checkboxes that can be used to toggle on or off
a large number of values. Each checkbox displays a name, and may also have an
associated tooltip value. Checkboxes can be highlighted, hidden, and re-ordered.

tf-multi-checkbox assumes that the names may be very long compared to the width
of the checkbox, and the number of names may also be very large, and works to
handle these situations gracefully.
